ICD-10 Code C82.3A – Follicular lymphoma grade IIIa, in remission (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C82.3A – Follicular lymphoma grade IIIa, in remission
What it is
This code identifies follicular lymphoma grade IIIa that is no longer active and is documented as in remission. Use it when the provider clearly states the lymphoma is in remission.
Clinical signs
Clinical features vary; refer to documentation. Follicular lymphoma may present with painless lymph node enlargement, but remission means current evidence of active disease is not documented.
When to use this code
Use this code when the record specifically states follicular lymphoma grade IIIa is in remission, including follow-up visits or surveillance after prior treatment. Code it only when the remission status is clearly documented by the provider.
Do not use for
Do not use it for active follicular lymphoma, uncertain remission status, or other lymphoma grades. Check documentation if the histology or remission status is not explicit.
Coding tip
Assign the remission code only when the provider documents remission; otherwise, query for clarification.
